My city recently had a 40-foot tall Rubber Ducky sculpture floating on the river. It had to stay in a small area because it wouldn’t have fit under bridges without hitting its head. We’d need someone to stand on the bridge an shout a warning. Oh, if only there were a short, simple warning word you could yell to keep someone from hitting their head! A word like, um, er…….gee, I just can’t think of one right now!
